Postnova Analytics:
FFF
Asymmetric Field Flow Fractionation
Postnova Analytics are based in Landsberg west of Munich, Germany
and in Salt Lake City, Utah, USA where FFF was first developed by
Professor Giddings. They are simply the world leaders in Field Flow
Fractionation technology (FFF) and especially in Asymmetric Flow FFF.
This is an ideal technology for separating nano-particles and biotech
materials prior to analysis by DLS or SLS and complements Zetasizer
SEC in flow mode for those who
want a flexible and powerful
system to size eluting particles
and molecules.
FFF-LS technology is applied to separate and characterize
biopolymers, synthetic macromolecules, proteins, antibodies,
liposomes and nanoparticles for molar mass, particle size and
branching conformation.
Phenom World
Desk Top Electron Microscopy
To complement light microscopy and laser particle analysers, electron microscopy offers unrivalled
information on size, shape and surface characteristics. The Phenom Pure, for example is highly affordable
yet can produce quality images in minutes.
Featuring a simple sample loading system, easy to use
software and a B&W camera to “look around” the sample you
get from 20X to 20,000 X magnifications—ideal for most
powders and many materials you cant take down to a
dedicated EM unit.
Or you can move up to a
Phenom Pro and extend the
range up to 100,000X
magnification, a colour camera
for 20x to 120x ranges and
5kV or 10kV acceleration
voltages.
